Mathematical Foundations of Computer Networking provides an intuitive yet rigorous introduction to these essential mathematical principles and techniques. Assuming a basic grasp of calculus, this book offers sufficient detail to serve as the only reference many readers will need. Each concept is described in four ways: intuitively; using appropriate mathematical notation; with a numerical example carefully chosen for its relevance to networking; and with a numerical exercise for the reader. The first part of the text presents basic concepts, and the second part introduces four theories in a progression that has been designed to gradually deepen readers’ understanding. Within each part, chapters are as self-contained as possible. The first part covers probability; statistics; linear algebra; optimization; and signals, systems, and transforms. Topics range from Bayesian networks to hypothesis testing, and eigenvalue computation to Fourier transforms. These preliminary chapters establish a basis for the four theories covered in the second part of the book: queueing theory, game theory, control theory, and information theory. The second part also demonstrates how mathematical concepts can be applied to issues such as contention for limited resources, and the optimization of network responsiveness, stability, and throughput. ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 管內機器人的開(kāi)發(fā) 摘要:針對石油天然氣長(cháng)輸管道焊接,采用焊口固定的全位置焊接,增加了大直徑、厚壁石油天然氣管道的焊接難度。在簡(jiǎn)要分析大直徑、厚壁石油天然氣管道焊接、探傷、檢測現狀的基礎上,結合焊接施工現場(chǎng)的環(huán)境特點(diǎn),介紹了一種適用于大直徑、厚壁石油天然氣管道焊接、探傷、檢測使用的管內機器人,著(zhù)重闡述了管內機器人的機械結構、控制系統硬件、控制軟件開(kāi)發(fā)等關(guān)鍵技術(shù)問(wèn)題。以及使用管內機器人作為管道自動(dòng)化作業(yè)平臺,以機電功能模塊,組裝各類(lèi)專(zhuān)用管道機器人,實(shí)現大直徑、厚壁石油天然氣管道焊接、探傷、檢測的自動(dòng)化。 ![]() ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
